位运算

This is a matter of procedure-bit computing, it is interesting, interested people do not look at the anti-.

详细说明：这是一个关于位运算的程序，很耐人寻味的，有兴趣的人不防看看。

Bit Arithmetic 64位算术运算 Modern 32-bit software frequently uses larger-than-32-bit integer data types for various purposes such as high-precision timers, high-precision signal processing, and many others.

现代32位的软件在表示高精度的计时器，进行高精度信号处理，及其他一些情况下经常使用高于32位的整型数数据类型。

Arrays and bit operation are adopted by the algorithm,the database will not be scanned for many times and the enormous candidate itemsets will not be produced.

该算法采用简单的数组和位运算，在执行关联规则的更新时，既不用多次扫描数据库，也不产生庞大的候选项集。

Bitwise operations, let alone when I have to explain them to somebody else!

按位运算，更不用说当我向他们解释别人！

Note that the status of the catalog is given in such a way that you can use bitwise operations to get multiple statuses from the one return value.

页请注意，该目录的地位是这样一种方式给您可以使用位运算来得到一个返回值的多个状态。

A new method to solve the combinatorial optimization problems with mixed evolutionary algorithm based on natural scale enumerative system coding was proposed in this paper. Elitism strategy, one-point crossover and Gaussian mutation were used in the algorithm. An ingenious method for operation among big parameters was designed, which can avoid overflow and simplify the operation.

在自然进位制编码的基础上，算法采用了遗传算法的单点交叉算子和进化规划的高斯扰动算子，并运用了精英保留策略；算法实现时采用逐位运算法实现大数值运算，避免了运算溢出，减少了运算量。

And several rough set operation algorithms are also offered in this paper,such as upper approximation set,lower approximation set,intersection, cardinal number and so on.

通过讨论二进制与粗糙集之间的内在联系，提出基于二进制的粗糙集运算理论，并借助二进制的位运算操作，给出粗糙集的上近似集和下近似集、等价类的交、集合的基数的运算算法。

All the ranges for the calculation of the 40 trillionth bit of Pi have been assigned, but quite a few people have dropped out, so I am reassigning their ranges.

所有对第40兆比特位运算的范围已全部分配，但是一部分人放弃了运算，因此我正在重新分配他们的部分。

In order to extend the effect and security of image encryption algorithm.An image encryption algorithm is presented based on three-dimension chaotic system and bit-computation.The permutation sequences and binary sequences are generated using three-dimension chaotic system.Firstly,the image is pretreated using chaotic system and permutation transformation,then the pixel's gray value's bit sequences are permuted using the permutation sequences generated before,at last,the pixel's gray value's bit sequences are computed by using XOR operating and the binary sequences.

为了改进图像加密算法的安全性和效率，提出了一种基于三维混沌系统和位运算的数字图像加密算法，利用三维混沌序列的坐标分量分别产生置换序列和二值序列，在对待加密图像进行预处理的基础上，先应用混沌置换序列对预处理的结果图像进行基于灰度值位序列的置换操作，然后再应用产生的二值序列对结果图像的灰度值位序列进行位异或加密运算。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
